Title: Improved transmission system
IPC: H04L12/28
Filed: 1962-05-15
Abstract: 984, 462. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 15, 1962 [May 26, 1961], No. 18698/62. Heading G4H. A communication system comprises a transmission line L, Fig. 1, having a central station S c  at one end and a terminal impedance R o  at the other end, and a plurality of remote stations S;, Si &c. connectible to the line, and is characterized in that each remote station includes both a line compensation impedance equal to the impedance of that part of the transmission line beyond the remote station and an impedance equal to the line terminal impedance R o , whereby when a remote station is connected to the line and that part of the line beyond the remote station is disconnected, a constant impedance is presented to the central station. In the system described any field station can call the central station but the central station cannot call the field stations. The calling sequence for remote station S i  is as follows. The call is initiated by the remote station connecting a higher impedance source A, Fig. 1b, to the line which raises the normally negative potential of the line. This is recognised by the central station which then, Fig. 1c, transmits a sequence of combinations of frequencies, each combination corresponding to a different remote station, until the combination corresponding to the calling remote station is reached at which time the calling station signals to central station thereby identifying itself. Also, at this time, the remote calling station disconnects the transmission line beyond it and connects its transmitter B, Fig. 1d, to the line. Thus the remote station has established communication with the central station and data can now be transferred.

Filed: 1966-04-28
Abstract: 1,107,445. Selenium rectifiers. SIEMENSSCHUCKERTWERKE A.G. 28 April, 1966 [28 April, 1965], No. 18791/66. Heading H1K. In a selenium rectifier the counter-electrode and the selenium layer contain thallium in a concentration ratio of from 1 : 100 to 1 : 10 by weight. The thallium in the counter electrode prevents the migration of the thallium from the selenium layer during manufacture and use. As shown, a rectifier is produced by dusting the surface of a nickel-coated aluminium plate 1 with powdered selenium heating to form a nickel selenide layer 2, evaporating-on a selenium layer 3 containing chlorine and tellurium, pre-crystallizing this layer by tempering, evaporating on a thin selenium layer 4 containing iodine and 200 to 2000 p.p.m. thallium, and spraying-on a counter-electrode 5 of 32/68 cadmium/tin alloy containing 10 to 100 p.p.m. thallium so that the concentration ratio of the thallium in the counter electrode 5 and the selenium layer 4 is 1 : 20. The device is heated to just below the melting-point of selenium to convert the selenium into the hexagonal form and to form a layer of cadmium selenide between layers 4 and 5. The device is then electrically formed. It is stated that it is known to include thallium in the counter-electrode and in the selenium layer in a concentration ratio of about 1 : 2.5.
